Curved space-time refers to the concept in physics that Einstein developed with his theory of general relativity. It describes how gravity affects the fabric of the universe and causes space and time to warp and curve around massive objects like planets and stars. Some synonyms for curved space-time that may be used in scientific literature and discussions include warped space-time, deformed space-time, bent space-time, and non-Euclidean space-time. These terms all refer to the same basic idea of the space and time we experience being influenced by the presence of matter and energy in the universe. Understanding the properties of curved space-time is essential to many areas of modern physics, including cosmology, black hole physics, and the search for a unified theory of everything.
